Explaining Ultra Wide Band
Ultra Wide Band will either be the beginning of a new age of
communication or the end of an old one, and probably both. UWB
is true digital radio communication, a series of very
short electrical pulses (billionths of a second) that
exist not on any particular frequency, but on
ALL frequencies simultaneously. It is just a
blast of electrical noise.
The key to turning that noise into communication lies in the
timing of the pulses that beat out a
code. ...
(UWB technology was originally developed for the military and
various U.S. and Soviet spy agencies as early as 1960).

... spread spectrum radio, .....operates today in every mobile
phone. But where spread spectrum used just a few dozen
frequencies and used them one at a time, UWB uses every
frequency there is, and uses them all at the same time,
which means the data-carrying capacity
of UWB is enormous.

UWB products will probably begin to hit the market in the next 18 to 24 months
.
In addition to radios, these products will include radar
and electronic positioning devices. DETECTING PEOPLE, OBJECTS
For soldiers entering a strange building, UWB radar can
show literally where all the bodies are, right through walls,
ceilings and floors.DETECTING LOCATION
As an electronic measuring device,
UWB is accurate to within 10 centimeters  much better than competing technologies like
Global Positioning System satellites,
and UWB can be used indoors, while GPS cannot.http://www.pbs.org/cringely/pulpit/pulpit20020124.html

International Accord on UWB crucial To thoroughly understand all the issues of concern, one would
have to spend weeks reading many thousands of pages of history
and technical analysis. In brief, however, the specific issues at
hand involve 1. cellular,
2. satellite
3. and land-based sensor network services
and the potential or perceived interference or degradation of
their signals. http://www.commsdesign.com/news/market_news/showArticle.jhtml?articleID=163100191

A Single Standard for UWB
In March, the U.S. Federal Communications Commission took a
significant step toward breaking an industry deadlock over
setting a single standard for a new wireless technology called
ultrawideband, or UWB. While traditional radio technologies
have transmitted and received analog signals only on specific
frequencies, UWB uses inexpensive computing power to send short
radio pulses across much of the radio spectrum. Because it
does not use a single frequency, UWB offers several advantages,
including the capacity to send large volumes of information
quickly and the ability to share frequencies and resist
interference. It is like breaking the cargo of a truck into loads
small enough to be carried on bicycles that can weave through a
traffic jam. The potential of the technology is to greatly
increase the capacity of the radio spectrum.
Wireless developers plan to work together to meld
Bluetooth, the short-range technology that links cellphones and
cordless headsets, with ultrawideband, The Associated Press
reported from New York
One major goal, according to the Bluetooth group, is to enable
short-range wireless compatibility between today's
Bluetooth-enabled devices and machines with UWB, which are not
expected to hit the market until at least next yearhttp://www.iht.com/articles/2005/05/04/business/uwb.php
D.C. Hospital gets UWB Aug. 19, 2004Parco
Wireless, a developer of an ultra-wideband RFID system for
healthcare facilities, has sold its first commercial
installation. In October, Parco will oversee the deployment of
more than 20 readers and around 100 tags for patients and staff
as well as tags for equipment throughout the emergency department
of the Washington Hospital Center in Washington, D.C.
Parcos real-time location system uses tags and readers
licensed from Multispectral Solutions, an ultra-wideband
(UWB) specialist based in Germantown, Md., combined with
Parcos own asset management software. The system allows
hospitals and clinics to track the status and exact location of
patients, staff and essential equipment. http://www.rfidjournal.com/article/articleview/1088/1/1/

Battery
RFid Ultra-wide band (UWB) thank you Alan TrombettaThis
system tracks small battery powered ID tags over a 30,000 square
foot area and reports their position to
within a foot!
No kidding, one foot. The implications for human tracking are
very interesting. A large network of
receivers could cover a city the same way
PCS towers give us cell phone coverage. If people are required to
carry tags that use this technology, it would be very easy to
correlate the data with video images to see who isn't carrying
their tag when out in public and who doesn't look like the tag's
owner. And of course locate anybody instantly.
Coupled with biometric-based access points (kind of like border
crossings) the system would be a tyrant's dream come true. If
someone were out to enslave the world, this would be a big help.
They don't have the biometric database, but wait and see how
retinal scans and fingerprint scans become a common part of our
new "homeland security".www.rense.com/general42/rf.htm

Optic
ChipThe polymers have been developed to act as modulators. Modulators
form the "bridge" between fibre-optic cables and
existing electronic devices - computers, TVs, etc.They
translate electrical information into data-packed beams of light.
Optic cables are currently not being used to their full potential
because of the poor interface with electronic devices. Organic
polymers developed by engineers at the University of Washington
and the University of Southern California translate electric
signals 10 times faster than current lithium based
devices.

They claim these provide such an enormous
bandwidth in which to fit information that a single chip
measuring little more than a millionth of an inch could handle
all a major company's telephone, computer, television and
satellite traffic. Yet, crucially, the device requires less than
a fraction of a volt of electricity to operate. http://news.bbc.co.uk/1/hi/sci/tech/704324.stm
